Die-Casting, method of producing castings of nonferrous metals in
which the molten metal is forced into a steel mold or die under
pressure. Zinc alloys are most widely today, followed by brass and
aluminum alloys and other nonferrous metals.

Forging, process of shaping iron and other malleable metals by hammering
or pressing them after making them plastic by application of heat.
Forging techniques are useful in the working of metal because the metal
can be given the desired form, and the process improves the structure of
the metal, particularly by refining the grain size of the metal.

The mold is made by repeated immersion of the pattern in a slurry of
refractory material. Spinning the mold after each immersion helps to
remove excess material and distribute the remaining material evenly.

Humans are inconsistent at this process but robots use the same timing
and spin force each time.

Thermoplastics are used in this process. They can be formed ormolded when heated. These plastics are
fed into injection molding machines, thermoforming machines or others to
form parts of a desired shape.

Typically, robots can unload parts from these machines, move the parts
to a trimming machine, and placing parts on a conveyor belt.

Prosthetics, mechanical contrivances adapted to reproduce the form, and
as far as possible, the function, of a lost or absent member. The
replacement of a missing body part by an artificial substitute is called
prosthesis; the branch of surgery dealing with prosthesis is
prosthetics.

Microprocessors are used to monitor neurons in the spinal cord making it
possible to create cybernetic or robotic arms and legs.
